I have been lurking here for a while and wanted to share some of the mods that I have started making to my DaVinci printer. I have done the Repetier Firmware upgrade, but in this thread I wanted to detail things about my extruder.

I have some spare parts laying around from another printer project, so I decided to install a "MK8" style heater block and nozzle. I have not been happy with the amount of radiated heat that the DaVinci nozzle produces into the parts (ABS). My theory is that this heater block and nozzle will produce higher quality parts. I am using one with a 12v 40W heater and a thermistor.
